# scales - SCALE Serialization

Making use of [type information](https://github.com/paritytech/scale-info) this library allows 

conversion to/from [SCALE](https://github.com/paritytech/parity-scale-codec) encoded data, 

specially useful when conversion is for dynamic types like JSON.

### From SCALE

`scales::Value` wraps the raw SCALE binary data and the type id within type registry 

giving you an object that can be serialized to any compatible format.

```rust

let value = scales::Value::new(scale_binary_data, type_id, &type_registry);

serde_json::to_string(value)?;

```

### To SCALE

Public methods from the `scales::serializer::*` module(feature `experimental-serializer`)

allow for a best effort conversion of dynamic types(e.g. `serde_json::Value`) to SCALE

binary format. The serializer tries to be smart when interpreting the input and convert it

to the desired format dictated by the provided type in the registry.

```rust

// simple conversion

let scale_data = to_vec(some_serializable_input); // or to_bytes(&mut bytes, input);

// with type info

let scale_data = to_vec_with_info(input, Some((&registry, type_id)));

// from an unordered list of properties that make an object

let input = vec![("prop_b", 123), ("prop_a", 456)];

let scale_data = to_vec_from_iter(input, (&registry, type_id));

```
